PEN-NIB.

Specification of Letters Patent.

Patented June 17, 1919.

Application filed August 9, 1916. Serial No. 113,997.

To all whom it may concern.

Be it known that I, GEORGE A. LOWDELL, a citizen of the United States,residing at San Diego, in the county of San Diego and State ofCalifornia, have invented certain new and useful Improvements inPen-Nibs; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to writing pen nibs, and its primary object is toadmit of the nib being conveniently removed from a pen holder withoutnecessitating the engagement of the nib by the hand of the operator,thereby preventing the hand being soiled by ink which adheres to thenib.

Another object of the invention is the provision of a nib that willadmit of the above object being carried out, and which can be as cheaplymanufactured as a nib of ordinary construction.

Other objects will appear and be better understood from that embodimentof my invention of which the following is a specification, referencebeing had to the accompanying drawing forming a part thereof, in which:

Figure 1 is a top plan view of the pen nib, showing the same removedfrom a holder.

Fig. 2 is a longitudinal sectional view, taken through Fig. 1.

Referring to the drawing in detail, the numeral 1 designates a penholder of ordinary construction, and the numeral '2 desig: nates, as anentirety, a pen nib of the improved construction. The nib shown in thedrawing resembles a nib of ordinary construction, but is provided at apoint intermediate the writing point and the shank of the nib with ashoulder 3. This shoulder 3 is of crescent shape, as shown in Fig. 1.The nib 2 and shoulder 3 are preferably formed by a single stamping, andthe metal forming the shoulder 3 is preferably forced outwardly, asshown in the drawing, but if desired the metal can be forced inwardly,so as to admit of the upper edge of the shoulder lying flush with theouter surface of the nib, or in other words a recess can be formed inthe upper side of the pen nib and having one wall of the recessproviding a shoulder.

When a nib, constructed in the manner of the foregoing, is associatedwith apen holder, and it is desired to remove the same withoutnecessitating the engagement of the nib by the operators hand, the endof the shank of another nib is positioned to and engaged behind theshoulder 3 on the nib 2 and which is associated with the pen holder, andoutward pressure exerted on the shoulder so as to effect withdrawal ofthe nib from the pen holder. It will, of course, be understood that ifdesired the shoulder can be engaged by the tip of one of the operatorsfingers, or thumbs so as to admit of the removal of the nib from theholder in this manner.

It is evident that various changes might be resorted to in theconstruction, form and arrangement of the shoulder without departingfrom the spirit and scope of the invention: Hence I do not wish to limitmyself strictly to the structure herein described and claimed.

Having thus described my invention what I claim as new, is:

As an article of manufacture, a writing pen nib having a curved shoulderof substantially U-shaped form in cross section pressed outwardly fromits body without severing the body to provide an abutment for receivingthe withdrawal force so as to permit of the withdrawal of the en nibfrom a pen holder without danger of the collapsing of the shoulder.

In testimony whereof I afl ix my signature in presence of two witnesses.

GEORGE A. LOWVDELL.
